Be prepared for your treatment

Make sure you drink plenty of fluids the day before your injection or infusion and eat a healthy breakfast that morning, unless otherwise directed by your doctor.

Before treatment

Your healthcare provider will give you medicines before each dose of DARZALEX FASPRO® or DARZALEX® to help reduce the risk of serious allergic reactions and other side effects due to the release of certain substances by your body (systemic).

You will be given medicines to help reduce the risk of side effects, such as:

  • Antihistamines to prevent an allergic reaction
  • Corticosteroids to prevent inflammation
  • Acetaminophen or similar medicine to reduce fever

You will be given a quick physical exam before your treatment, which may include checking your pulse, weight, and blood pressure.

Do not receive DARZALEX FASPRO® or DARZALEX® if you have a history of a severe allergic reaction to daratumumab, hyaluronidase (DARZALEX FASPRO®), or any of the ingredients in either treatment.

Your healthcare provider will do blood tests to match your blood type before you start treatment with DARZALEX FASPRO® or DARZALEX®.

DARZALEX FASPRO® and DARZALEX® can affect the results of blood tests to match your blood type. These changes can last for up to 6 months after your final dose of DARZALEX FASPRO® or DARZALEX®. Tell all of your healthcare providers and blood transfusion center personnel that you are being treated with DARZALEX FASPRO® or DARZALEX® before receiving blood transfusions.

Before you receive DARZALEX FASPRO® or DARZALEX®, tell your doctor or care team about all of your medical conditions, including if you:

  • have a history of breathing problems
  • have had shingles (herpes zoster)
  • have ever had or might now have a hepatitis B infection

    DARZALEX FASPRO® and DARZALEX® could cause hepatitis B virus to become active again. Your healthcare provider will check you for signs of this infection before, during, and for some time after treatment with DARZALEX FASPRO® or DARZALEX®. Tell your healthcare provider right away if you get worsening tiredness or yellowing of your skin or white part of your eyes

  • are pregnant, planning to become pregnant, or have a female partner who may become pregnant

    DARZALEX FASPRO® and DARZALEX® may harm your unborn baby. Tell your healthcare provider right away if you become pregnant or think that you may be pregnant during treatment with DARZALEX FASPRO® or DARZALEX®. See Important Safety Information for additional considerations around pregnancy for DARZALEX FASPRO® and DARZALEX®

  • are breastfeeding or plan to breastfeed

    – It is not known if DARZALEX FASPRO® and DARZALEX® pass into your breast milk. You should not breastfeed during treatment with DARZALEX FASPRO® or DARZALEX®. Talk to your healthcare provider about the best way to feed your baby during treatment with DARZALEX FASPRO® or DARZALEX®

  • have hereditary fructose intolerance (HFI)

    – DARZALEX® (infusion) contains sorbitol. Sorbitol is a source of fructose. People with HFI cannot break down fructose, which may cause serious side effects

After treatment

fatigue Icon

Go home and rest. It’s not unusual to be tired after treatment. So it might be a good idea to have a friend drop you off and pick you up—or stay and keep you company. If you have any symptoms of an injection- or infusion-related reaction, get medical help right away.

steroids icon

You will be given medicines, like an oral corticosteroid, to take once you go home to help reduce the risk of delayed reactions. If you have a history of breathing problems, such as chronic obstructive pulmonary disease (COPD), you may be given additional medicines, such as bronchodilators or inhaled corticosteroids.
